CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of and claims priority to U.S. patent application Ser. No. 17/394,015 filed Aug. 4, 2021, which is a continuation of U.S. patent application Ser. No. 16/100,153 filed Aug. 9, 2018, now U.S. Pat. No. 11,089,906, which claims the benefit of U.S. Provisional Application No. 62/653,185 filed Apr. 5, 2018. The entire contents of each of the applications listed above are incorporated herein by reference.

FIELD OF THE DISCLOSURE

An insulated container for maintaining the temperature of food and/or beverage contained therein is generally described. More specifically, an insulated container having a vacuum-insulated outer container and a removable glass insert that protects a user's lips from contacting the outer container, is described.

BACKGROUND OF THE DISCLOSURE

Maintaining the temperatures of food and beverages is vital to enjoying the complete characteristics they have to offer. Various types of containers are used to maintain the temperatures of the contents (food or beverage) of such containers. For instance, when beverages are placed in such containers, ice is often added to the beverages, such that that they are in contact with the ice and become cooler based on the contact. A disadvantage with such coolers is that once the ice melts, it dilutes the beverage contained therein and the beverage may become warm. Another disadvantage is that once the beverage has been in the container for some time, large amounts of liquid (i.e., condensation) may form on the external surface of the container, which may make the container slippery and cause it to fall out of the user's hands. This may be dangerous to the user and others nearby, particular when the containers are made of glass. In some instances, when the contents of the container are hot (such as soup or other heated food), the container may be too hot and uncomfortable to the user's hands.

Some insulating containers may be made of metals. While such metallic containers may provide insulative properties, a disadvantage with these metallic containers is that they may result in the leaching of metals into the food or beverages contained therein. Some metallic containers may be made of stainless steel, which is often manufactured using a nickel alloy, such as nickel-iron. Iron and nickel have been found to leach into some alkaline and acidic foods and beverages, which may be hazardous to a user's/consumer's health.

In view of the disadvantages associated with presently available food and beverage containers, there is a need for an insulating container that maintains the temperature of food or beverages, and prevents the formation of condensation on an external surface of the container. Additionally, there is a need for an insulating container that maintains the temperature of hot or cold food and/or beverages contained therein, while also reducing a user's exposure to leached metals.

DETAILED DESCRIPTION

For purposes of illustrating features of the embodiments, examples will now be introduced and referenced throughout the disclosure. Those skilled in the art will recognize that these examples are illustrative and not limiting, and are provided purely for explanatory purposes.

FIGS. 1A-3B, 6A-7 and 9A-9B illustrate an insulated container 10, and it associated components. The insulated container 10 may include a double-walled structure 20, which may be vacuum-insulated. The type of material selected to form the double-walled structure 20 may be based at least in part on the material's capability for repeated and long-term use. According to an aspect, the double-walled structure 20 is composed of a metal, such as stainless steel. The type of metal selected for the double-walled structure may be based, at least in part, on its strength. For example, the double-walled structure 20, when made of stainless steel, may have superior strength-to-weight ratio, which may help to form a more stable insulated container 10, as compared to containers composed of aluminum, glass, ceramic, or various plastic materials.

The double-walled structure 20 includes a closed end/base 22 and an open end/rim portion 24. As illustrated in FIGS. 1B and 1E, the closed end 22 is generally planar and may include a raised platform/coaster 70. The coaster 70 may be dimensioned so that it covers less than a total surface area of the closed end 22. The coaster 70 may include and/or be formed from materials that reduce friction between the double-walled structure 20 and smooth/slippery surfaces, such as glass, granite, wood, and the like. According to an aspect, the coaster 70 is formed from a variety of materials, including rubber, plastic, and foam, as would be understood by one of ordinary skill in the art. The coaster 70 may help stabilize the insulated container 10 when the insulated container 10 is positioned on slippery surfaces. The coaster 70 may help prevent potential spill of contents of the insulated container 10 and, in some instances, damage of the surface on which it is placed.

A side wall 26 extends between the closed and open ends 22, 24. The side wall 26 and the closed end 22 together form a hollow interior/internal space 28, which receives materials or additional structures/containers therein. According to an aspect, the side wall 26 has a generally circular cross-section (see, for example, FIG. 6B) along at least a portion of its length L1 (FIG. 1C). As illustrated in FIGS. 1D-1E, the outer diameter of the double-walled structure 20 may increase from the closed end 22 to the open end 24. According to an aspect and as illustrated in FIGS. 1A-1C, the side wall 26 is contoured so that it has a generally convex outer surface 27 close to the closed end 22. In this configuration, the outer diameter of the double-walled structure 20 may increase from the closed end 22 to an intermediate position 26 a along the side wall 26 (FIGS. 1A-1B, and 2 ), and decrease from the intermediate position 26 a to the open end 24, so that the double-walled structure 20 has a contoured side wall 26. In an embodiment, and as illustrated in FIG. 1D and FIG. 1E, the side wall 26 is contoured so that it has a generally convex outer surface 27 close to the open end 24. The contoured side wall 26 may provide increased available space (that may be subjected to a vacuum) between walls of the double-walled structure.

As illustrated in FIG. 2 , FIGS. 6B-6C and FIG. 6E, the double-walled structure 20 may include at least one stepped portion 29 formed in its inner surface 25. The stepped portion 29 is illustrated as partially extending from the open end 24 towards the closed end 22. The inner surface 25 of the double-walled structure 20 may be generally planar, with the stepped portion 29 having an increased inner diameter. As illustrated in FIG. 2 , the double-walled structure 20 has a first inner diameter ID2 along the stepped portion 29, and a second inner diameter ID3 extending from the stepped portion 29 to the closed end 22. The first inner diameter ID2 may be greater than the second inner diameter ID3, which may help facilitate securing an additional structure within the hollow interior 28, as described in detail hereinbelow. According to an aspect and as illustrated in FIG. 2 , the second inner diameter ID3 may be substantially uniform from the stepped portion 29 towards the closed end 22 of the double-walled structure 20. In an embodiment, the second inner diameter ID3 may gradually decrease from the stepped portion 29 towards the closed end 22 of the double-walled structure 20 to receive a glass structure 30 (as seen in, for instance, FIGS. 6D-6F).

According to an aspect and as illustrated in FIG. 7 , the double-walled structure 20 may include a plurality of indentations 50 formed in its outer surface 27. The indentations 50 may be recessed areas/depressions formed in the side wall 26. The indentations 50 may be recessed from the overall structure, and according to one aspect the indentions 50 maintain an outwardly rounded/curved surface (i.e., bowed area) or a flattened area. In the illustrated embodiment, the indentations 50 extend from the closed end 22 of the double-walled structure 20 to an intermediate position between the closed end 22 and the open end 24. However, other possibilities are contemplated. In an embodiment, the indentations 50 are configured as rectangular-shaped areas, the longer sides of the rectangular-shaped areas extending from the closed end 22 towards the open end 24. The indentations 50 partially extend from the outer surface 27 inward towards the inner surface 25 of the double-walled structure 20, and may function as grip areas/surfaces for placement of the user's fingers to help provide a more secure/stable grip for a user of the insulated container 10. According to an aspect and as illustrated in FIGS. 6A-6D and FIG. 7 , the indentions 50 may include one of more raised tactile portions 52 (such as stamped letters, numbers, or markings) that further help to enhance the user's grip on the insulated container 10. The tactile portion 52 may include raised or indented (not shown) areas. The indentations 50 may also enhance the user's comfort when holding the insulated container 10, accessing the contents of the insulated container 10, or pouring or drinking from the insulated container 10. In some embodiments, the indentations 50 may span more than 50% of a length L1 of the double-walled structure 20. The indentations 50 may span from about 50% to about 85% the total length L1 of the double-walled structure 20. According to an aspect, the indentations 50 may be from about 30 mm to about 40 mm wide.

In an embodiment and as illustrated in FIGS. 9A and 9B, the indentations 50 are bilateral indentations 50 (i.e., a pair of indentations) formed on opposite portions of the outer surface 27 of the double-walled structure 20. It is to be understood, however, the number of indentations 50 provided on the outer surface 27 may be modified. For instance, a single indentation 50 may be formed in the double-walled structure 20. According to an aspect, 3, 4, 5, or more indentations 50 may be provided.

As illustrated in FIGS. 1A-1E, FIGS. 3A-3B, FIGS. 4A-4B, FIGS. 6A-6B, FIGS. 6D-6E and FIG. 7 , the insulated container 10 further includes a glass structure 30. The glass structure 30 is configured for receiving food and beverage therein, so that the food and beverage does not contact the double-walled structure 20. The glass structure 30 is dimensioned to be removably arranged within the hollow interior 28 of the double-walled structure 20. When arranged and secured within the double-walled structure 20, the glass structure 30 may be protected from breakage, which may occur if a glass vessel slips and falls from a user's hands. According to an aspect, the glass structure has a length L3 that is less than (see, for instance, FIG. 6D) or substantially the same as (not shown) the length L1 of the double-walled structure 20.

According to an aspect, the glass structure 30 includes a body 36 having an open upper end 37 and a base end (second end or closed end) 34. The body 36 may be formed with a variety of shapes that facilitate arrangement of the glass structure 30 within the double-walled structure 20. According to an aspect and as illustrated in FIG. 6D-6F, the body 36 may taper from the upper end 37 towards the base end 34, such that the body 36 has a frustoconical shape. In an embodiment and as illustrated in FIG. 6A, the body 36 is configured as a substantially cylindrical structure. The dimensions of the glass structure 30, and its upper end 37, range from amounts effective for retaining food and/or beverage within the glass structure 30, and removing the food and/or beverage therefrom.

The glass structure 30 further includes a sipping portion 32 extending from the open upper end 37 of the body 36. According to an aspect and as illustrated in FIG. 1C, FIGS. 3A-3B, FIGS. 4A-4B, FIGS. 6A-6B, and FIGS. 6D-6F, the sipping portion 32 includes a shoulder 31 b, a sipping end 31 a, and a side wall 33 extending between the sipping end 31 a and the shoulder 31 b. According to an aspect, the side wall 33 extends around the upper end 37 of the glass structure 30. The side wall 33, including the shoulder 31 b protrudes from the upper end 24 of the double-walled structure 20. According to an aspect and as illustrated in FIG. 6F, the side wall may be substantially straight/linear. In an embodiment, the side wall 33 of the sipping portion 32 flares outwardly, with an outer diameter OD4 of the sipping end 31 a being greater than an outer diameter OD1 of the shoulder 31 b. According to an aspect, the sipping portion 32 flares inwardly, with the outer diameter OD4 of the sipping end 31 a being less than the outer diameter OD4 of the shoulder 31 b. According to an aspect and as illustrated in FIGS. 7-8 , the side wall 33 is outwardly bowed/curved, which may enhance a user's comfort when drinking or sipping from the container 10.

As illustrated in FIG. 6F, the shoulder 31 b of the sipping portion 32 is seated on top of the open end 24 of the double-walled structure 20. The sipping end 31 a of the sipping portion 32 extends away from the open end 24, thereby preventing users from directly contacting their lips to the double-walled structure 20. This may eliminate or substantially reduce the risk that users will directly contact their lips with the material used to make the double-walled structure (such as metallic materials).

The glass structure 30 further includes an outer diameter OD2 along the body 36, extending from the upper end 37 to the base end 34. According to an aspect the outer diameter OD2 of the body 36 is less than the outer diameters OD1, OD4 of the sipping and shoulder ends 31 a, 31 b of the sipping portion 32. The outer diameter OD2 of the body 36 may be less than a first inner diameter ID2 of the double-walled structure 20, so that the body 36 of the glass structure 30 can be disposed in the hollow interior 28 of the double-walled structure 20, with only the sipping portion 32 outwardly extending therefrom. According to an aspect, when the glass structure 30 is disposed in the hollow interior 28 of the double-walled structure 20, a total length L2 of the container 10 is greater than the length L1 of the double-walled structure 20.

As illustrated in FIG. 1A, FIG. 1D and FIG. 6F, the glass structure 30 may further include one or more stepped interior portions (recesses or contours) 39 at the sipping portion 32. The stepped interior portion 39 is formed in the inner surface of the glass structure 30. The stepped interior portion 39 may aid in enhancing a user's comfort when drinking from the container.

As illustrated in FIGS. 3A-3B, FIGS. 4A-4B, FIGS. 6A-6B, and FIGS. 6D-6E, the insulated container 10 further includes a deformable flange 40. The deformable flange 40 is positioned around the body 36 of the glass structure 30, so that when the glass structure 30 is positioned within the hollow interior 28 of the double-walled structure, the deformable flange 40 is compressed between the glass structure 30 and the inner surface 25 of the double-walled structure. The deformable flange 40 may help to protect the glass structure 30 from breaking when the glass structure 30 is secured in the double-walled structure 20 by the deformable member 40.

According to an aspect, the inner surface 25 of the double-walled structure 20, along the stepped portion 29, includes a plurality of ribs (not shown) that receive the protrusions 44 of the deformable flange 40. This may help facilitate a semi-permanent attachment of the double-walled structure 20 to the glass structure 30.

FIGS. 4A-4B and FIGS. 6A-6B, 6D and 6F illustrate the generally positioning of the deformable flange 40. The deformable flange 40 may be positioned on the glass structure 30 from the second end, and moved up towards the shoulder end 31 b of the sipping portion 32. FIG. 4A illustrates the deformable flange 40 extending around the body 36 of the glass structure 30 in a spaced apart configuration from the sipping portion 32. As illustrated in FIGS. 4B, 6A-6B, 6D and 6F, the deformable flange 40 may be positioned adjacent the shoulder end 31 b of the sipping portion 3230.

FIGS. 5A-5D illustrate the deformable flange 40 in more detail. The deformable flange 40 includes a main body 42 that is able to conform to the shape of the glass structure 30. In an embodiment, when positioned around the body 36 of the glass structure 30, the deformable flange 40 has a generally cylindrical (FIG. 6A) or a generally conical or frustoconical shape (FIGS. 6D and 6F).

It is contemplated that the deformable flange 40 may be secured to the glass structure 30 by a friction fit. Additional securing mechanisms may be provided on surfaces of the deformable flange 40 to aid with securing the flange 40 onto to the glass structure 30 and to double-walled structure 30. According to an aspect, an inner surface 43 of the deformable flange 40 includes a plurality of threads for engaging with corresponding threads formed on the body 36 of the glass structure 30 (not shown). As illustrated in FIG. 5B, FIG. 5C and FIG. 5D, the inner surface 43 of the deformable flange is smooth, which may facilitate ease of placement around the body 36 of the glass structure 30. The threads of the deformable flange 40 and optionally, the threads on the body 36 of the glass structure 30, may be one of continuous threads or interrupted threads. As used herein, “continuous threads” may mean a non-interrupted threaded closure having a spiral design (e.g., extending around the skirt like a helix), while “interrupted threads” may mean a non-continuous/segmented thread pattern having gaps/discontinuities between each adjacent thread.

According to an aspect and as illustrated in FIGS. 5A-5D, the threads may be a plurality of protrusions 44 that extend from an outer surface 41 of the body 42. The plurality of protrusions may be continuous/uninterrupted (i.e., formed contiguously around the main body 42 of the flange 40. According to an aspect and as illustrated in FIGS. 5B-5D, the protrusions 44 may be interrupted (i.e., having multiple segments, or the protrusions 44 being spaced apart from each other, that extend generally around a circumference of the body 42).

The protrusions 44 of the deformable flange 40 are flexible and engage the inner surface 25 of the double-walled structure 20. According to an aspect, the deformable flange 40 engages the inner surface 25 of the double-walled structure 20, at the stepped portion 29. The deformable flange 40 may be composed of any material that is flexible, and may be repeatably compressed and/or is able to maintain compression for an extend period of time. According to an aspect, the deformable flange 40 is composed of at least one of rubber, plastic, and silicone. The deformable member may be made by formed by an injection molding process, or in any other suitable manner.

The deformable flange 40 has an inner diameter ID1 and an outer diameter OD3. The inner diameter ID1 of the deformable flange 40 may be substantially the same size as, or slightly less than, the second diameter OD2 of the body 36 of the glass structure 30. This allows the deformable flange to be secured to the body 36 without slipping off. According to an aspect, the outer diameter OD3 of the deformable flange 40, includes the protrusions 44, and is greater than the inner diameter ID2 of the double-walled structure 20. When the deformable flange 40 is secured to the glass structure 30, and the glass structure 30 including the deformable flange is arranged in the hollow interior 28 of the double-walled structure 20, the deformable flange 40 is compressed between the inner surface 25 of the double-walled structure 20 and the glass structure 20.

According to an aspect and as illustrated in FIG. 3B, the container 10 includes a gasket 60. The gasket 60 may be secured between the glass structure 30 and the double-walled structure 20. The gasket 60 engages with the inner surface 25 of the double-walled structure 20, at the stepped portion 29, and the body 36 of the glass structure 30, adjacent the lip portion 33. The gasket 60 may be utilized with or without the deformable flange 40 positioned between the structures 20, 30. According to an aspect, when the container 10 includes the gasket 60 and the deformable flange 40, the gasket 60 is adjacent the lip portion 33 of the glass structure 30, and the deformable flange 40 is adjacent the gasket 60, such that the gasket 60 is sandwiched between the shoulder portion 31 b of the sipping portion 32 of the glass structure 30 and the deformable flange 40.

The gasket 60 may help secure the glass structure 30 to the double-walled structure 20. According to an aspect and as illustrated in FIG. 3C, the gasket 60 includes a plurality of threads 62 extending along at least one of its inner 61 surface and outer surface 63. The threads 62 may be continuous threads or interrupted threads, selected, at least in part, on the corresponding threads formed on at least one of the body 36 of the glass structure 30 and the inner surface of the double-walled structure (at the stepped portion). The gasket may be dimensioned similar to the deformable flange 40, described hereinabove, with inner and outer diameters that facilitate its ability to seal areas between the glass structure 30 and the double-walled structure 20, as well as secured the glass and double-walled structures 30, 20 together.

According to an aspect, the gasket 60 helps seal against the introduction of food contents and fluids in areas between the glass structure 30 and the double-walled structure 20. The gasket 60 may help to absorb vibration around the glass structure 30, and prevent the glass structure 30 from breaking in the event that the container 10 falls from a surface or out of a user's hands. The gasket 60 may be formed from plastic, silicone, rubber, or any type of material that provides sealing and shock absorption properties. According to an aspect, the gasket 60 may be positioned between the shoulder end 31 b of the sipping portion 32 and the deformable member 40.

Embodiments of the disclosure are further directed to a vacuum-insulated container 10′. The vacuum-insulated container/insulated container 10′ may be configured substantially as described hereinabove with respect to FIGS. 1A-3B, 6A-7 and 9A-9B.

As shown in FIG. 8 and according to an aspect, the vacuum-insulated container 10′ includes an inner container 21 a, and an outer container 21 b spaced apart from the inner container 21 a (the inner and outer containers 21 a, 21 b may function as the double-walled structure 20 described hereinabove and illustrated in FIGS. 1-3B, 6A, 6B and 7 ). The inner and outer containers 21 a, 21 b may both be formed of a metal, such as stainless steel. A plurality of indentations 50, substantially as described hereinabove and illustrated in FIG. 7 may be formed in an external surface 27 of the outer container 21 b. The indentations 50 facilitate a comfortable use of the vacuum-insulated container 10′. The inner container 21 a has a generally cylindrical shape, while the outer container 21 b has is contoured so that it is generally bell-shaped. A gap 23 is formed between the inner and outer containers 21 a, 21 b. The gap 23 between is devoid of air by virtue of creating a vacuum between the inner and outer containers 21 a, 21 b. The created vacuum reduces the number of molecules present in the gap 23 that could potentially transfer heat by conduction.

Each of the inner and outer containers 21 a, 21 b includes a closed end 22′, 22″ and an open end 24′, 24″. A side wall 26′, 26″ extends between each of the respective closed ends 22′, 22″ and respective open ends, 24′, 24″ of the containers 21 a, 21 b. The inner container 21 a and the outer container 21 b are coupled and sealed along their respective open ends 24′, 24″ so that external air is prevented from passing through the seal and into the gap 23. This may retard the transference of heat by conduction and/or convection, so that food particulates and/or beverages positioned in vacuum-insulated container 10′ do not gain or lose heat.

The inner container 21 a includes at least one stepped portion 29 formed in its inner surface 25. As described hereinabove with respect to the double-walled structure 20, the stepped portion 29 partially extends from the open end 24′ towards the closed end 22 of the inner container 21 a. The stepped portion 29 is configured for engaging at least one of a deformable flange 40 and a gasket 60, which secures a glass structure 30 that is inserted into the inner container 21 a. The deformable member 40 and gasket 60 may be configured substantially as described hereinabove and illustrated in FIGS. 3C and 5A-5D. According to an aspect, the inner container 21 a includes a first inner diameter ID2 along the stepped portion 29, and a second inner diameter ID3 extending from the stepped portion 29 to the closed end 22′. The first inner diameter ID2 is greater than the second inner diameter ID3, which facilitates the positioning/placement of the deformable flange 40 and/or the gasket 60 adjacent the stepped portion 29.

The vacuum-insulated container 10′ further includes a glass structure 30 arranged within a hollow interior 28 of the inner container 21 a, and the deformable flange 40 circumferentially extending around the glass structure 30. In this embodiment, the glass structure 30 is similar to the glass structure 30 illustrated in FIGS. 1A-1E, FIGS. 3A-3B, FIGS. 4A-4B, FIGS. 6A-6B, and FIGS. 6D-6F, and described hereinabove. Thus, for purposes of convenience and not limitation, the various features, attributes, and properties, and functionality of the glass structure 30 and the deformable flange 40 discussed in connection with FIGS. 1A-1E, FIGS. 3A-3B, FIGS. 4A-4B, FIGS. 6A-6B, and FIGS. 6D-6F are not repeated here.

The glass structure 30 is dimensioned to partially fit in the inner container 21 a of the vacuum-insulated container 10′, with its sipping portion 32 extending from the hollow interior 28 of the inner container 21 a. As illustrated in FIG. 8 , the shoulder end 31 b of the sipping portion 32 extends over the respective open ends 24′, 24″ of the containers 21 a, 21 b. It is contemplated that the upper end 37 of the body 36 of the glass structure 30 may be secured to the open ends 24′, 24″, at least in part by the deformable flange 40 extending around the circumference of the glass structure 30 and being secured at the stepped portion 29 of the inner container 21 a.

According to an aspect, the outer diameter OD2 of the body 36 of the glass structure 30 is less than the first inner diameter ID2 of the inner container 21 a, which helps to ensure that the body 36 may be received in the inner container 21 a. According to an aspect the outer diameter OD2 of the body 36 is less than the outer diameters OD1, OD4 of the sipping and shoulder ends 31 a, 31 b of the sipping portion 32. The shoulder portion 31 b may be seated at the open ends open end 24′, 24″ of the inner and outer containers 21 a, 21 b.

The plurality of protrusions 44 of the deformable flange 40 engage the inner surface 25 of the inner container 21 a, and helps to retain the glass structure 30 within the hollow interior 28. According to an aspect, when the outer diameter OD3 of the deformable flange 40 is greater than the inner diameter ID2 of the inner container 21 a, the deformable flange 40 is compressed between the body 36 of the glass structure 30 and the inner surface 25 of the inner container 21 a, which may help secure the inner container 21 a, the deformable flange, and the glass structure 30 together.

The present disclosure, in various embodiments, configurations and aspects, includes components, methods, processes, systems and/or apparatus substantially developed as depicted and described herein, including various embodiments, sub-combinations, and subsets thereof. Those of skill in the art will understand how to make and use the present disclosure after understanding the present disclosure. The present disclosure, in various embodiments, configurations and aspects, includes providing devices and processes in the absence of items not depicted and/or described herein or in various embodiments, configurations, or aspects hereof, including in the absence of such items as may have been used in previous devices or processes, e.g., for improving performance, achieving ease and/or reducing cost of implementation.

The phrases “at least one”, “one or more”, and “and/or” are open-ended expressions that are both conjunctive and disjunctive in operation. For example, each of the expressions “at least one of A, B and C”, “at least one of A, B, or C”, “one or more of A, B, and C”, “one or more of A, B, or C” and “A, B, and/or C” means A alone, B alone, C alone, A and B together, A and C together, B and C together, or A, B and C together.

In this specification and the claims that follow, reference will be made to a number of terms that have the following meanings. The terms “a” (or “an”) and “the” refer to one or more of that entity, thereby including plural referents unless the context clearly dictates otherwise. As such, the terms “a” (or “an”), “one or more” and “at least one” can be used interchangeably herein. Furthermore, references to “one embodiment”, “some embodiments”, “an embodiment” and the like are not intended to be interpreted as excluding the existence of additional embodiments that also incorporate the recited features. Approximating language, as used herein throughout the specification and claims, may be applied to modify any quantitative representation that could permissibly vary without resulting in a change in the basic function to which it is related. Accordingly, a value modified by a term such as “about” is not to be limited to the precise value specified. In some instances, the approximating language may correspond to the precision of an instrument for measuring the value. Terms such as “first,” “second,” “upper,” “lower” etc. are used to identify one element from another, and unless otherwise specified are not meant to refer to a particular order or number of elements.

As used herein, the terms “may” and “may be” indicate a possibility of an occurrence within a set of circumstances; a possession of a specified property, characteristic or function; and/or qualify another verb by expressing one or more of an ability, capability, or possibility associated with the qualified verb. Accordingly, usage of “may” and “may be” indicates that a modified term is apparently appropriate, capable, or suitable for an indicated capacity, function, or usage, while taking into account that in some circumstances the modified term may sometimes not be appropriate, capable, or suitable. For example, in some circumstances an event or capacity can be expected, while in other circumstances the event or capacity cannot occur—this distinction is captured by the terms “may” and “may be.”

As used in the claims, the word “comprises” and its grammatical variants logically also subtend and include phrases of varying and differing extent such as for example, but not limited thereto, “consisting essentially of” and “consisting of.” Where necessary, ranges have been supplied, and those ranges are inclusive of all sub-ranges therebetween. It is to be expected that variations in these ranges will suggest themselves to a practitioner having ordinary skill in the art and, where not already dedicated to the public, the appended claims should cover those variations.

The terms “determine”, “calculate” and “compute,” and variations thereof, as used herein, are used interchangeably and include any type of methodology, process, mathematical operation or technique.

The foregoing discussion of the present disclosure has been presented for purposes of illustration and description. The foregoing is not intended to limit the present disclosure to the form or forms disclosed herein. In the foregoing Detailed Description for example, various features of the present disclosure are grouped together in one or more embodiments, configurations, or aspects for the purpose of streamlining the disclosure. The features of the embodiments, configurations, or aspects of the present disclosure may be combined in alternate embodiments, configurations, or aspects other than those discussed above. This method of disclosure is not to be interpreted as reflecting an intention that the present disclosure requires more features than are expressly recited in each claim. Rather, as the following claims reflect, the claimed features lie in less than all features of a single foregoing disclosed embodiment, configuration, or aspect. Thus, the following claims are hereby incorporated into this Detailed Description, with each claim standing on its own as a separate embodiment of the present disclosure.

Advances in science and technology may make equivalents and substitutions possible that are not now contemplated by reason of the imprecision of language; these variations should be covered by the appended claims. This written description uses examples to disclose the method, machine and computer-readable medium, including the best mode, and also to enable any person of ordinary skill in the art to practice these, including making and using any devices or systems and performing any incorporated methods. The patentable scope thereof is defined by the claims, and may include other examples that occur to those of ordinary skill in the art. Such other examples are intended to be within the scope of the claims if they have structural elements that do not differ from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal language of the claims.
